Title: There and back again: the compasses monarchs use to get to and return from Mexico
Description: How do monarch butterflies orient southwards during the fall migration in order to reach the overwintering sites in Mexico? How do monarchs re-orient during the spring remigration in order to return northwards? This webinar will provide an overview of how monarchs use various sensory-based orientation mechanisms for directionality. In particular, the webinar focuses on describing how monarchs employ two types of compasses that they can use to help guide them during migration, namely a time-compensated sun compass and an inclination-based magnetic compass. In addition to reviewing our basic knowledge of monarch navigation, this webinar will also describe how the use of these compasses by monarchs is potentially now under threat due to contemporary environmental stressors, such as climate change and sensory noise pollution.
Presenter: Dr. Patrick Anthony Guerra; Assistant Professor in the Department of Biological Sciences at the University of Cincinnati.
